Zones in which interpersonal interactions can take place are known as proxemics

Edward Hall, a famous anthropologist coined the term ‘Proxemics. He was interested in understanding how humans use space in communication. Thus, proxemics is about the study how humans using space during their communication with others. It is about how close one stand to someone, whether one touches each other and how comfortable we feel are all part of the study of proxemics.

Which food molecule (monosaccharide, polysaccharide, lipid, or protein) would you eat if...
torisob [31]
<span>You needed a quick boost of energy - MONOSACCHARIDE

You wanted to grow strong nails, you haven't eaten in days - PROTEIN

You wanted to grow healthy hair - PROTEIN

You had a race tomorrow afternoon - POLYSACCHARIDE 

You were getting ready for hibernation - LIPIDS

You wanted to get bigger muscles - PROTEIN 

Your meal will be in a week - LIPIDS

CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants. 

PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.

LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>

The​ half-life of​ carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only ​% of the​ carbon-14
Leokris [45]

Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.

<h3>What is Carbon?</h3>
  • Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
  • Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
  • Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve
kkurt [141]

Answer:

The correct matches are:

  1. In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
  2. In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
  3. In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
  4. In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

  • Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
  • Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
  • Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
  • Since, NADH is donating its H+, it is being oxidized to NAD+.
